Boston Celtics guard Ron Harper Jr. set career-highs in points, assists, and steals in Sunday’s win over the Orlando Magic. His inspired performance, in what was an improbable victory for Boston’s stay-ready crew, served as a fitting finale for Harper Jr.’s first full season in green.
“It's just been really rewarding knowing that the time that I'm putting in, the effort that I'm putting in, doesn't go unnoticed in the building by my teammates, my coaching staff, front office,” Harper Jr. shared after posting 27 points, four rebounds, three assists, and three steals against the Magic.
The 26-year-old rejoined the Celtics for a training camp deal back in September -- a year after he was waived by Boston and signed to their G-League affiliate, the Maine Celtics. He ended up finishing the season with the Detroit Pistons who poached him from Maine in January of 2025.
Training camp ended differently for Harper Jr., this time. His Exhibit-10 deal turned into a two-way contract in the days leading up to Boston’s regular-season opener.
“It was a little bit of a gamble,” Harper Jr said of his return to the Cs. “But even last year, when I got waived off of the Exhibit-10, and I was in the G League, it was never any hard feelings. I felt like I learned a lot that training camp, being around a team that had just won a championship, those experiences, it’s unmatched. You see how those guys grind, see how they play the game. You see how they work out. You see how they approach the day-to-day. It’s just something I try to take with me throughout my journey.”
A month later, Harper Jr. was named G-League Player of the Week.
“I had a great stay in Maine when I was there, won Player of the Month, me and my teammates were able to compete in the showcase tournament in Orlando. That was a great experience.“
He played his final game for Maine on Feb. 1. Three days later, he made his first-career start for Boston in their win over the Houston Rockets. That night he nearly logged a double-double -- posting 11 points and nine rebounds -- and was tasked with guarding Kevin Durant.
Harper Jr.’s NBA opportunities began to pile up over the last two months of the season. He appeared in 22 of the Celtics’ final 31 games, compared to just seven of the first 51.
“Trust doesn't just come from what you do in the games,” head coach Joe Mazzulla said of Harper Jr.’s emergence. “You know, it comes from what you do in workouts. It comes from what you do in the film session. It comes from what you in Maine. It comes what you do on an optional day. If you're working one on one with your coach, like trust happens in so many ways.”
Whether the opportunities were large or small, it didn’t matter. Harper Jr. made the most of his playing time.
Every time took the floor, he made the case for his next appearance -- showcasing defensive versatility by guarding the likes of Durant and Victor Wembanyama, and proving to be a reliable perimeter threat.
Sunday’s season finale was just another example. Harper Jr. laid the foundation for Boston’s upset victory with 12 first-quarter points to help his squad keep pace with the Magic. He poured in 10 more as part of the Celtics’ third quarter avalanche, where they flipped the game on its head and outscored Orlando 42-20.
His career night came just over a week after he inked his first standard NBA contract, which includes a team-option for next season.
“This year has just been really, really rewarding just being able to come back to Boston, earn a roster spot, and be a part of a great organization. I feel like it's paid dividends for me and my career. You know, I'm just really grateful to be in this situation.”
